| Abstract Scope |
Novel nanocomposites with superior mechanical and multifunctional properties can be created by integrating unique nanofillers with 1D, 2D, and 3D architectures. Such nanofillers include boron nitride nanotubes (BNNTs), 2D semi-conductors, and 3D boron nitride nanoplatelet (BNNP) foams. The addition of these nanomaterials induces complex deformation mechanisms which can only be visualized through in situ investigations. Using in situ techniques, mechanical tests were conducted in a scanning electron microscope, thus allowing for real-time imaging at multiple length scales while simultaneously collecting load-displacement curves. Localized indentation of nanotube branches, nodes, and clusters provided intrinsic material properties and interfacial interactions. Bulk composites were examined through high-load indentation, scratch tests, and micro-tensile tests to gain insight into the mechanical strength and failure mechanisms of these 3D architectures. The role of temperature on mechanical strength and deformation was examined using high-temperature indentation. These results can provide engineers with useful information for future advanced composites. |
